Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626258, here are decompositions:

11 + 31626247 = 31626258
29 + 31626229 = 31626258
61 + 31626197 = 31626258
67 + 31626191 = 31626258
127 + 31626131 = 31626258
149 + 31626109 = 31626258
179 + 31626079 = 31626258
239 + 31626019 = 31626258

Showing the first eight; more decompositions exist.
